1. Photosynthesis

2. Seeds Purpose of Seeds... Seed Parts Produce a new plant Plumule
Radicle
Cotyledon
Seed Coat

3. Roots Purpose of Roots… Root Types Anchor Store Food Collect Water
Fibrous
Taproot

4. Flower Purpose of Flower… Flower Parts To reproduce/make a seed
Pistil (stigma, style, ovary, ovule, egg)
Stamen (anther, filament, pollen grain, sperm)
Petals
Sepals

5. Stem Purpose of Stem… Structures found in Stems…
Establish basic shape of plant
Position leaves
Structures found in Stems…
Xylem  transports water from roots to leaves
Phloem  transports nutrients from leaves to roots

6. Leaves Purpose of leaves… Leaf Layers PHOTOSYNTHESIS! Epidermis…
Outside layer of leaf
Protects
Waterproof
Mesophyll…
Middle of leaf
Contains chloroplasts (where photosynthesis occurs)

7. Epidermis-Blue
Guard Cells-Green
Mesophyll-Red
Xylem-Yellow
Phloem-Orange

9. What is photosynthesis?
Process in which plants make their own food.

11. PLANTS.... NEED MAKE SUNLIGHT GLUCOSE (ENERGY) OXYGEN CARBON DIOXIDE
WATER
MAKE
GLUCOSE (ENERGY)
OXYGEN

12. Photosynthesis Process
1. Light from the sun strikes the plant’s leaves.
2.The chlorophyll in the cells of the plant absorbs light from the sun

13. 3. The sun’s energy splits the water(H2O) molecules into hydrogen (H) and oxygen (O).

14. 4. Carbon dioxide (CO2) enters leaves through holes called stomates.

15. 5. The hydrogen joins with the carbon dioxide to make glucose/food (sugar).

16. 6. The sugar is carried to other parts of the plant.
7. The extra oxygen is released into the air and is what we need to breathe.

17. Photosynthesis Equation
Light + Carbon Dioxide (CO2) + Water (H2O)
Glucose (C6H12O6) + Oxygen (O2)

21. Stomates Holes on the LOWER EPIDERMIS Lets in… Lets out…
Carbon Dioxide
Lets out…
Water
Oxygen

23. Guard Cells
Cells on either side of stomate (opening) that open and close the hole to allow materials in and out of leaf.
